Abstract

The procedure that enable the preservation of the compressive stress-induced microcracks and bonding characteristic in interfacial transition zone (ITZ) of rubberized concrete under applied load was investigated. The materials used were fine aggregate, coarse aggregate, shredded rubber obtained from waste tires and cement. Water/Binder ratio (0.55) and cement content (418 kg/m ) were kept constant in all samples. Four designated rubber contents were selected 5%, 10%, 15% and 20% by volume of total aggregate. The SEM samples were collected from the fracture areas after the compressive strength tests. All samples chosen for the SEM analysis were coated with silver/gold for electrical conduction. The SEM images of rubberized concrete showed that cracks generated from voids between rubber tire and cement paste in the concrete. It was found that these cracks usually start from ITZ between rubber tires and cement paste because of poor bonding characteristic around rubber tires and cement paste. 3
